For example, the game.controller.* addons did not get installed and Kodi was not able to resolve the dependencies and download them automatically. You have to download these addons manually for each core (quite a tedious task).

Several solutions: include this patch or add instructions to press the "Get all" button in the controller configuration dialog.

The best solution would be to modify Kodi to just-in-time install the needed controller profiles. It already does just-in-time installation for libretro cores, so this shouldn't be too hard a task.

For the rest of your bugs, can you open GitHub issues in the game add-ons repo or my xbmc repo? That makes the bugs easier to track then reading through a potpourri forum post.
